EUVD-2026-53678

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap...

DEBIAN-CVE-2026-19028

H5Zfilterfletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a sizet underflow. This allows attackers to cause a denial o...

H5Zfilterfletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a sizet underflow. This allows attackers to cause a denial o...

Linux Distros Unpatched Vulnerability : CVE-2026-19026

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - H5Zfilternbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cdvalues0 through cdvalues4 without validating that cdvalues is non-NULL or that cdnelmts is at...

Linux Distros Unpatched Vulnerability : CVE-2026-19027

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index int...

CVE-2026-19025

H5Olayoutdecode in H5Olayout.c in HDF5 through 2.3.0 does not validate that a chunked dataset's stored chunk-layout dimensionality matches its dataspace rank when an existing dataset is opened, whereas this check is performed only at dataset-creation time. This allows attackers to cause a denial ...

DEBIAN-CVE-2026-19023

Untrusted pointer dereference in the renderbinoutput function in the h5dump tool in HDF5 before 2.3.0 allows attackers to cause a denial of service via a variable-length string dataset with more than one element dumped in binary mode, which corrupts the per-element stride calculation and causes...

CVE-2026-19028

The CVE-2026-19028 vulnerability affects HDF5 up to version 2.3.0, specifically the H5Z__filter_fletcher32 function in H5Zfletcher32.c. The data length used for the checksum is computed by subtracting the 4-byte trailing checksum from the input buffer size without verifying that the buffer is at ...

CVE-2026-19028 HDF5 integer underflow in Fletcher32 filter leads to massive out-of-bounds read

H5Zfilterfletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a sizet underflow. This allows attackers to cause a denial o...

CVE-2026-19027

The CVE-2026-19027 entry describes an out-of-bounds heap read in HDF5 before 2.3.0 due to the N-Bit filter decompression routines. Specifically, H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic in H5Znbit.c advance a read index into the compres...

CVE-2026-19026

The CVE-2026-19026 issue affects HDF5 up to v2.3.0, specifically H5Z__filter_nbit in H5Znbit.c. The code dereferences cd_values[0] through cd_values[4] without verifying that cd_values is non-NULL or that cd_nelmts >= 5, exploiting the fixed size of the filter header. This can cause a denial o...

CVE-2026-19025

The CVE-2026-19025 entry concerns HDF5 versions up to 2.3.0. It describes a flaw in H5O__layout_decode within H5Olayout.c where a chunked dataset’s stored chunk-layout dimensionality is not validated against its dataspace rank when an existing dataset is opened (validation exists only at dataset ...
